Caspofungin acetate is a lipopeptide antifungal drug. It is a member of a new class of antifungals termed the echinocandins. It works by inhibiting the enzyme (1→3)-β-D-glucan synthase and thereby disturbing the integrity of the fungal cell wall. Caspofungin acetate for injection was originally approved by FDA in USA, and the EMEA in Europe, in 2001.
